Please ask the national standard rules are which

1, snooker billiard table inner edge length 350 cm, inner edge width 175 cm, height 85 cm. 22 colored balls *** divided into 8 colors, red ball 15 (1 point), yellow ball 1 (2 points), green ball 1 (3 points), brown ball 1 (4 points), blue ball 1 (5 points), pink ball 1 (6 points), black ball a (7 points), white ball 1 (main ball). The main ball may be used before kick-off. 2. Before the tee-off, the home ball may be placed at any point in the teeing area (D-zone). The tee shot must first directly or indirectly hit a red ball. The ball must first be hit directly or indirectly with a red ball, and then with a colored ball until all the red balls are in the bag. One of the colored balls is returned to the original spot. Then hit the yellow, green, brown, blue, pink and black balls in descending order according to the score of the colored balls. 3. When only the black ball is left on the table, hitting the black ball into the pocket or committing a foul will end the game. At this time, if the score of both players is equal, the black ball will be placed again for the deciding period of the game, and at this time, no matter who hits the black ball into the pocket or commits a foul, the game will be ended. The following fouls shall be penalized (4 points if the score is less than 4 points, and 4 points if the score is greater than 4 points): hitting the ball before the ball stops; hitting the ball more than once with the club head; hitting an empty ball; hitting the target ball with the main ball; hitting the ball with the feet off the ground; hitting the ball off the ground, but not placing the main ball into the teeing area (D zone); hitting the ball into a jumping ball; hitting the ball into bounds; the main ball hitting the ball first and then hitting the ball not in the bag; hitting the ball with the clothes, body, club, or other equipment; hitting the ball with a ball in the bag; or hitting the ball in the bag and hitting the ball with the club head. When striking the ball, the player's clothing, body, club and wearables touch the ball on the table. 5. Seven points are awarded for the following fouls: hitting the red ball into the pocket and then hitting the ball before it is designated; hitting the red ball after it has been scored and then hitting the red ball without declaring the color ball; and using the white ball instead of the white ball as the main ball. Snooker Trivia 1) Basic Snooker Play and Determination of Winners and Losers Snooker*** is played with 22 balls, of which 15 are red, 6 are colored (1 each of black, pink, blue, brown, green and yellow) and 1 is white. The red and colored balls are used to score points and the white ball is used to hit the red and colored balls. Before each start, the balls are laid out in the form of Figure 1. Prior to the kickoff, both teams can flip a coin to determine who kicks off first. During the kickoff, the kicker can place the white ball anywhere in the kickoff area to hit the red ball. The white ball must then be hit from wherever the white ball stops. Each team must first score a red ball and then choose a favorable colored ball to play. When the ball is scored, it is taken out and placed back in its original position (i.e. where it was before the kick-off). Next, the red ball is played, the colored ball is played, and so on until all the red balls are in the bag. After that, the colored balls must be played in a certain order. That is, the yellow ball is played first, then the green ball, brown ball, blue ball, pink ball and black ball. At this point, when a ball is scored, there is one less ball on the table (it is no longer necessary to remove the ball from the bag and return it to its original position), until all the balls are in the bag and the white ball is left on the table, then the game is over. 2) The process from the beginning until all the colored balls and red balls have been hit into the pocket is called a game. If a player fails to score a goal, or hits a bad ball, he must give way to the other player. The process of scoring consecutive goals is called "one shot". The winner of each game is determined by the number of points scored by each side, with the winner being the one who scores more points. Points are scored in two ways: either by scoring a goal or by penalizing the opponent for a mistake. One point is awarded for scoring a red ball (also known as "1 degree"), two points for scoring a yellow ball, three points for a green ball, four points for a brown ball, five points for a blue ball, six points for a pink ball, and seven points for a black ball. Therefore, both players will try their best to put the black ball into the pocket as often as possible. If the white ball fails to touch any of the red balls when playing the red ball, the penalty is 4 points; if it touches a colored ball by mistake, the penalty is according to the score of the colored ball, but the minimum penalty is 4 points. That is, if the black ball is touched, the penalty is seven points, and if the yellow ball is touched, the penalty is four points. Similarly, if a player fails to hit a colored ball, he is penalized according to the score of the ball, and if he misses a higher-scoring ball, he is penalized according to the higher score, with a minimum penalty of four points. Therefore, after scoring a red ball and before playing a colored ball, in theory, the player has to declare which colored ball he is going to play. In practice, if the ball to be played is obvious, no declaration is necessary, but if it is not obvious, it must be declared, or an automatic 7-point penalty is applied. As in diagram 2, the player must first declare which colored ball (brown, blue or pink) he is going to play. If the white ball is mistakenly hit into the pocket, there is a minimum penalty of 4 points, or the first higher scoring ball touched before the white ball went into the pocket. If the white ball is in the pocket, the next player may hit the white ball anywhere on the teeing ground. Penalty points are not deducted from the penalized player's score, but are added to the opponent's score. Since it is also possible to score points from the mistakes of both players, a player who feels that he or she has no chance of scoring will try to make a snooker. The so-called \"snooker\" is a situation in which the next player cannot hit the ball directly, but has to take a difficult shot such as a rebound or a curve, and is therefore liable to make an error which results in a penalty point. A match can be decided in one or three, five or seven sets. In contrast, the final of the World Professional Championship is played over thirty-five games. If, at the end of the match, there is a tie, the traditional method of deciding the winner is to leave the black ball on the black tee and the white ball on the tee, and both sides decide who will play first by tossing a coin, with the winner being the one who scores the black ball first. 2) Some common rules of snooker and their application The rules of snooker are so complicated that even world champion masters often fail to grasp them all. However, these rules can usually be acquired through practice. The following are some common rules that often confuse novices. Fumbled Balls: The minimum penalty for a fumbled ball is 4 points, or the actual score of the ball if it is a colored ball of 4 points or more. (1) Hitting the ball off the table. (2) Hitting the ball with both feet off the ground at the same time. (3) The white ball jumps over the center ball to hit the target ball. (4) The ball on the table is touched by any object or any part of the body other than the striking end of the cue ball. (5) The cue ball strikes the white ball more than twice in succession during the stroke. (6) The cue stick, the white ball and the target ball are in contact at the same time. This often happens when the white ball and the target ball are too close together . For example, when the distance between the two balls is less than 2.5 centimeters, it is very difficult to make a shot without a foul unless the target ball is lightly touched, as in Figure 4. So when the white ball is close to the target ball, the hitter is only allowed to hit the white ball away from the target ball. In this particular case, the white ball is considered to have hit the target ball by opening it up to the target ball. A good golfer will often take advantage of this opportunity to make a safety shot or a snooker. Because it is possible to play the white ball without the white ball hitting any other ball, it is easy to make a safety and snooker, as in Fig. 5. When a player misses a ball, and then a snooker appears on the table, preventing the next player from hitting the red ball, the next player may play a colored ball of his choice as a red ball, which is called a free ball. If this ball is pocketed, it is treated as a red ball and scored as one point, and the player playing next plays the colored ball as usual. If the red balls on the table have been played out, the situation is such that the next player cannot hit the ball directly, the next player can choose a ball to play, and this ball is called a free ball, and the score of the free ball in the pocket is calculated according to the lowest score left on the table, and then play the color balls in the usual order. If a player misses a ball and puts the other player at a disadvantage, the other player has the right to ask the player who missed the ball to play the ball again. This rule, like the free throw rule, is to prevent either side from intentionally playing a fumbled ball to profit from it. However, before deciding to allow the fumbler to play, one must be sure that every ball on the table has no chance, and the level of play of the fumbler must be taken into account. Unconscious Saving: An unconscious saving penalty may be awarded after a player has played an errant ball, if the referee believes that the ball should have been played. In this case, the winning team has the following options: (1) return the ball to the position it was in before the ball was fumbled and ask the fumbler to replay the ball; (2) ask the fumbler to play the ball again from its current position; (3) play the ball from its current position; and (4) play a free shot if there is a snooker on the table. When the color ball falls out of the pocket and is placed back on the table, if the original spot of the ball is occupied by another ball, the ball is placed in the empty spot of the highest scoring color ball at that time. As shown in Figure 6, when the green ball is in the pocket and its original spot is occupied by another ball, the empty spots on the table are the brown ball spot, the yellow ball spot and the pink ball spot, and the green ball should be placed on the pink ball spot. If all the spots are occupied, the ball should be placed in a line perpendicular to the bottom edge of the table, closest to its home spot, and not touching any other ball. Stalemate: When the referee considers that a stalemate has developed, the referee states to both players that if there is no significant change in the situation within a few rounds, the game is null and void and has to be restarted. In addition, snooker has developed a number of unique rules: (1) Both players decide who will start by tossing a coin, but take care not to spin the coin on the table to avoid damaging the tablecloth. (2) When both players are playing, try to keep quiet, and take care not to stand behind the pocket that the other player is aiming at. Or any other position that may affect the playing team. (3) In friendly matches and regular matches, there is no referee on the court. In this case, after the opponent scores the color ball, you should help to put the color ball back on the table, and take the initiative to report the score. (4) When you make a mistake, even if the referee does not see it, you should take the initiative to declare it. (5) Have a proper attitude and good manners. Like golf, snooker requires a high level of sportsmanship and gentlemanly behavior.
